How Accurate are Recalls of Self-Weighing Frequency? Data from a 24-Month Randomized Trial.

ABSTRACT:

Introduction

Self-weighing is an important component of self-monitoring during weight loss. However, methods of measuring self-weighing frequency need to be validated. This analysis compared self-reported and objective weighing frequency.

Methods

Data came from a 24-month randomized controlled trial. Participants received 12 months of a behavioral weight-loss program and were randomly assigned to (1) daily self-weighing, (2) weekly weighing, or (3) no weighing (excluded from analysis). Objective weighing frequency was measured by Wi-Fi enabled scales, and self-reported weighing frequency was assessed every 6 months by questionnaire. Objective weights were categorized to match the scale of the self-report measure.

Results

At 12 months, there was 80.8% agreement between
